体外研究
(In Vitro)

EAI045 potently inhibits EGFR Y1173 phosphorylation in H1975 cells (EC50=2 nM), but not in HaCaT cells. EAI045 is an inhibitor of the L858R/T790M mutant with 1000-fold selectivity versus wild type EGFR at 1 mM ATP. Profiling of EAI045 against a panel of 250 protein kinases reveals exquisite selectivity; no other kinases are inhibited by more than 20% at 1 μM EAI045[1]. EAI045 has high potency and selectivity for L858R/T790M mutation. In L858R/T790M-mutant NSCLC cell line H1975 cells, EAI045 decreases but does not completely abolish the EGFR autophosphorylation. In stably transfected NIH-3T3 cells harboring the L858R/T790M EGFR mutant, EAI045 shows the same activity. In L858R-mutant H3255 cells, EAI045 exhibits moderate activity. In the HaCaT cells, a keratinocyte cell line with wild-type EGFR, EAI045 does not show any activity of inhibiting EGFR phosphorylation. It confirms the selectivity of EAI045 for mutant EGFR[2].

体内研究
(In Vivo)

In a genetically engineered mouse model of L858R/T790Mmutant-driven lung cancer , remarkable tumor regression is observed in L858R/T790M-mutant mice treated with the combination of EAI045 and cetuximab. No response is seen in those mice treated with EAI045 alone. The same effect is seen in both L858R/T790M/C797S- engineered Ba/F3 cells and in mice carrying the L858R/T790M/C797S tumor xenografts. These assays clearly show that EAI045 can overcome resistance from acquired T790M and C797S mutations[2].

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.52 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (6.52 mM); 悬浊液; 超声助溶

    此方案可获得 2.5 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Cell Assay
[1]

For the experiment studying the effect of EGF pre-treatment on EAI045 target modulation, H1975 cells are harvested and plated in 0.5% FBS/RPMI Pen/Strep. On the following day, cells are pre-treated with 0.5% FBS/RPMI media with or without 10 ng EGF/mL for 5 minutes. Compound is added and assay is carried out[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Mice: Cetuximab is administrated at 1 mg/mouse every other day by intraperitoneal injection. The TL, TD and TLCS mice are monitored by MRI to quantify lung tumor burden before being assigned to various study treatment cohorts, which are non-blinded and not formally randomized. All treated mice had an equal initial tumor burden. MRI evaluation is repeated every 2 weeks during treatment. The animals are imaged with a rapid acquisition with relaxation enhancement sequence in the coronal and axial planes with a 1-mm slice thickness gating with respiratory rates. The tumor burden volumes are quantified[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
